1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Increasing evidence suggests that the beta gamma-subunit dimers of heterotrimeric G proteins play a pivotal role in transducing extracellular signals. The recent construction of G beta null mutants (g beta-) in Dictyostelium provides a unique opportunity to study the role of beta gamma dimers in signaling processes mediated by chemoattractant receptors. We have shown previously that g beta- cells fail to aggregate; in this study, we report the detailed characterization of these cells. The g beta- cells display normal motility but do not move towards chemattractants. The typical GTP-regulated high affinity chemoattractant-binding sites are lost in g beta- cells and membranes. The g beta- cells do not display chemoattractant-stimulated adenylyl cyclase or guanylyl cyclase activity. These results show that in vivo G beta links chemoattractant receptors to effectors and is therefore essential in many chemoattractant-mediated processes. In addition, we find that G beta is required for GTP gamma S stimulation of adenylyl cyclase activity, suggesting that the beta gamma-dimer activates the enzyme directly. Interestingly, the g beta- cells grow at the same rate as wild-type cells in axenic medium but grow more slowly on bacterial lawns and, therefore, may be defective in phagocytosis.
